David,
It might be worth going over a set of Use Cases to frame where transformation 
(in both directions) between an HL7 message and RDF might be used.

In the FHIR - RDF scenario of consuming system and producing system (the 
information source) the following patterns are options for consideration:

        Consumer        Producer        Option                  Discussion
1       FHIR            FHIR                                    Standard FHIR 
exchange - does not involve RDF (it is added for completeness)
2       FHIR            RDF             Producer converts       Producer 
accepts FHIR request and converts it to RDF query then converts response RDF to 
FHIR 
3       FHIR            RDF             Consumer converts       Consumer 
converts FHIR request to RDF request and converts response from RDF to FHIR
4       RDF             FHIR            Producer converts       Producer 
accepts RDF request and converts it to FHIR query then converts FHIR response 
to RDF response
5       RDF             FHIR            Consumer converts       Consumer 
converts RDF request to FHIR request and converts response from FHIR to RDF
6       RDF             RDF                                     Standard RDF 
exchange to agreed ontologies

I believe that the most likely options are 2 & 5 which make all the conversions 
happen in the RDF based system.

Tony Mallia

Subject: San Antonio meeting planning -- Input please!

At the San Antonio HL7 meetings we will have a 1.5 hour meeting time in 
the HL7 ITS work group on Monday Jan 18 at 9:00-10:30am.   This will be 
an opportunity with the rest of the ITS work group, and I would like people's 
input about how they think we should make use of that time. 
Bear in mind that aside from that scheduled time slot, we also plan to get 
together informally to work intently on FHIR RDF, as permitted by participants' 
availability.  Hence the availability survey:
https://www.surveymonkey.com/s/S7B8HTY

Some potential topics for our 1.5 hour time slot with the rest of ITS:

  - Update on the RDF group's progress in general

  - Have someone lead a hands-on FHIR RDF hacking demo

  - Hash out FHIR RDF/ontology requirements

  - Other?

Please let me know your thoughts about what you think would be good to include 
in that 1.5 hour slot.

Thanks,
David Booth
